MUMBAI, India, July 31 -- Intellectual Property India has published a patent application (202617067939 A) filed by Herrenknecht AG on May 30, 2026, for Method And Device For Determining A Geotechnical Parameter Of An Excavated Material.
Inventors include Heim, Andre; Kassel, Andreas; Thienert, Christian; Gutberlet, Lara; Budach, Christoph; and Mller, Pierre.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: The invention relates to a method for determining at least one geotechnical parameter of an excavated material from a tunnel-boring machine, wherein: the excavated material is fed onto a conveyor device (2) for transporting the excavated material; an impact body (5) is arranged in a conveyor flow (3) of the excavated material so that it is at least partly immersed in the excavated material; the excavated material in the conveyor flow (3) has a flow speed which is either predetermined or measured; a measured variable corresponding to a force exerted by the excavated material of the conveyor flow (3) on the impact body (5) is measured; a time sequence of measured values ??of the measured variable is recorded and the at least one geotechnical parameter is determined from a portion of the sequence of measured values ??by inputting the portion of the time sequence of measured values ??into a data processing apparatus and processing it using this apparatus such that at least one output value corresponding to the at least one geotechnical parameter is output; and the processing of the measured values ??is based either on the predetermined flow speed or a value for the measured flow speed is input and taken into account when the measured values are processed.
